With six international design awards and over 100 patents, the ROIDMI S1 is bristling with innovation. The efficient 100,000 rpm motor and LG/Samsung developed lithium battery cleans up to 350 square metres on a single charge. Pioneering tool design, outstanding filtration and class-leading dust/air separation put the ROIDMI S1 at the forefront of cordless vacuum cleaner design. The S1 equipped with ROIDMI Filtration system, captures 99% of mold, pollen, dust mite, dog and cat allergens, down to 0.3 microns. . This means that the S1 is equipped with a small air purifier ensuring the exhaust air is cleaner than the air it draws in. The ROIDMI App offers a host of information and advanced controls. You can check the battery status, keep an eye on filter maintenance and replacement and access additional cleaning modes. Functions like a calorie counter and the amount of m2 vacuumed are coming to the app soon.
